Medicare Advantage provider directories (doctor in-network checks)

1,572 of 5,561 2027 Medicare Advantage plans (MA and MA-PD, 28%) have a public provider directory loaded, so /MedicarePlans can show whether your doctor is in network. Source: each organization's CMS-required public provider directory (Da Vinci Plan-Net FHIR API), crawled slowly and without registering for anything on a plan's behalf.

Organizations whose directory API needs a developer registration or key are not loaded yet. "Estimated" mappings match a plan to a directory network by name or product line rather than by CMS plan id, so they are flagged on every doctor result. In-network status comes from each Medicare Advantage organization's public provider directory (CMS-required Plan-Net). Directories can be out of date and a plan not listed here may still cover the doctor: always confirm with the plan and the doctor's office before enrolling.

3,163 counties, 286 Part D formularies. Provider networks for Medicare Advantage plans are being added organization by organization (Humana first); where a plan shows no network data, confirm doctors with the plan. Browse 2027 Medicare plans by county.
